ABSTRACT:
A three-dimensional non-woven fabric with a thermally activated adhesive surface well suited for use as a facing fabric for covering a fibrous mat. The fabric comprises two adjoining fiber layers, namely an adhesive layer including bond-forming fibers fusible at a predetermined temperature and a facing layer of fibers having a considerably higher melting temperature than the bond-forming fibers. The fibers of both layers are mechanically engaged one with another and are arranged flat-wise in bundles interconnected at junctures by protuberant fiber packings disposed in a staggered relationship throughout the fabric. Bond-forming fibers are concentrated in the apex portions of the fiber packings to form the thermally activated adhesive surface. The invention also extends to a process for manufacturing the three-dimensional non-woven fabric, based on the so-called "rosebud" technique for producing foraminous webs. The invention further comprehends a molded fibrous mat article with a non-woven fabric facing layer, and a method for producing the article.
